using parameters

 public class DemoCustomSQL : UIControllerBase
    {
        public readonly NumberColumn OrderId = new NumberColumn("OrderId","6");
        public readonly TextColumn ShipName = new TextColumn("ShipName","50");
        public readonly TextColumn ShipCity = new TextColumn("ShipCity","50");

        DynamicSQLEntity dynamicSql;
        public DemoCustomSQL()
        {
            dynamicSql = new DynamicSQLEntity(Shared.DataSources.Northwind1, @"
select orderid, shipName, shipcity
  from Orders
Where ShipCity = ':1'");

            From = dynamicSql;
            dynamicSql.Columns.Add(OrderId, ShipName, ShipCity);
            dynamicSql.AddParameter(() => "London");//:1
        }
        public void Run()
        {
            Execute();
        }
        protected override void OnLoad()
        {
            View = () => new Views.DemoCustomSQLView(this);
        }
    } 

Adding another parameter

 public class DemoCustomSQL : UIControllerBase
    {
        public readonly NumberColumn OrderId = new NumberColumn("OrderId","6");
        public readonly TextColumn ShipName = new TextColumn("ShipName","50");
        public readonly TextColumn ShipCity = new TextColumn("ShipCity","50");

        DynamicSQLEntity dynamicSql;
        public DemoCustomSQL()
        {
            dynamicSql = new DynamicSQLEntity(Shared.DataSources.Northwind1, @"
select orderid, shipName, shipcity
  from Orders
 Where ShipCity = ':1'
   and orderid = :2");

            From = dynamicSql;
            dynamicSql.Columns.Add(OrderId, ShipName, ShipCity);
            dynamicSql.AddParameter(() => "London");//:1
            dynamicSql.AddParameter(() => 10532);//:2
        }
        public void Run()
        {
            Execute();
        }
        protected override void OnLoad()
        {
            View = () => new Views.DemoCustomSQLView(this);
        }
    }
